SEVERIN HALVORSEN, OF SEATTLE, WASHINGTON, ASSIGNOR TO THE NEWSPAPER STUFFING MACHINES COMPANY, OF SEATTLE, WASHINGTON, A CORPORATION OF WASHINGTON.

PAPER-OPENING DEVICE FOR NEWSPAPER-STUFFING MACHINES.

Application filed November 1, 1915.

To all whom it may concern:

Be it known that I, SEVERIN HALVORSEN, a-citizen of the United States, and resident of the city of Seattle, county of King, and State of WVashington, have invented certain new and useful Improvements in Paper- Opening Devices for Newspaper-Stuffing Machines, of which the following is a specification.

My invention relates to newspaper stuffing.

machines, and more particularly to the means employed for opening the cover section for the insertion of the filler sections.

The object of my invention is to produce a device for the opening of the cover sections in stuffing newspapers, which device shall be an improvement upon existing devices both in the manner of performing its work and in the compactness and the simplicity of its parts.

My invention comprises certain parts and combination of parts which will be hereinafter described, and particularly pointed out in the claims.

In the accompanying drawings I have shown my invention embodied in the form of construction which is now preferred by me. I

This invention is an improvement in paper opening devices shown in my application for patent for a newspaper stufiing machine, Serial Number 33,311, filed June 10, 1915. The mechanisms used for delivering the paper sections to the opening mechanism, and the mechanisms employed in caring for the paper after stuffing may be those passed from chambers 11 in which stacks of 7 these sections are placed. The mechanisms by which these papers are removed from the stacks one at a time, and placed to the feed rolls, 1 and 10, are immaterial. to my present invention, and I have not herein illustrated them. Any mechanism which will removea single paper at a time and present it to the rolls, 1 and 10, will answer for this purpose.

The rollers 12-12 are associated with the rollers 1-1, and feed tapes 14- pass about these, thus forming feed and controllingmembers for the paper section, whereby the latter is properly delivered to the opening mechanism. Similarly rollers 13 and feed tapes 15 deliver papers from another stack to be inserted within the cover section when the latter is open. I have shown a third set V of feed tapes 16, which deliver a second insert section. The number of insert sections delivered for placing within the open cover section may be whatever is desired.

The cover section, which is delivered by the operation of the tape 14, is received between guide fingers 2 and 20. The guide fingers 2 extend downward and are bent to form a curve 21, which raises outside of the path of movement of the periphery of a feeding segment 3. These guide fingers 2 then extend laterally and on a downward incline under the path of movement of the feeding segment 3, and have their other end secured at 22.

Two sets of feeding segments 3 and 30 are employed, these being mounted upon shafts 31 and 32, which are placed in parallel relation and at such distance apart that the peripheries of the two sets of feeding seg ments will be separated just enough to make a firm contact with the paper section which. is to be opened when the latter is passing between them. This relation is clearly shownin Figs. 3 and A. At the points where the guide fingers 2 pass the point where'the feed segments engage the papers to feed them, which point is on and adjacent the line adjoining the two shaft lines 31 and 32, the. guiding fingers 2 lie slightly within the path of movement with the upper feeding segment 3.

The feeding segments 3 and 30 are alike in construction, and differ only in the fact that the segment 30 is of larger radius than the segment 3. The shafts 31 and 32 to which these feeding segments are secured are turned at the same rate this being accomplished by any suitable means. The means preferred for this purpose and herein shown consist of two gear wheels 33, which are equal in diameter. The teeth of these wheels should be of such character and length as to permit a slight variation of the distance between the shafts 31' and 32, such adjustment being desirable to accommodate different thicknesses ofcover sections used.

One of the feeding segments is shown in detail in Figs. 6, 7, and 8. The peripheral extent of these feeding segments is determined by the widths of the paper sections being fed, in the direction of their line of feed. This peripheral extent is approxi mately that of the width of such paper sections. Each segment is provided with a groove in its side face, as is shown. at 34, and in this is placed a segmental block 4.

This segmental block A is shown separately in Figs. 9, 10, and 11. It is of such thickness in a radial direction as to radially fill the curve 34, while in the direction parallel the axis, upon, which the segment turns, it is of less width than the space in the segmental disk in which it is placed. This block has a coned or beveled peripheral surface, which acts as a cam for the adjustment of the feeding pins when the segment block is adjusted. The outer wall of the segment disk is rovided with a series of projections or bores which lie outsideof thebeveled surface 40 of block 4,

In each of these bores is placed a needle 5, the stem of which is surrounded with a coiled spring 50, which acts against the inner surface of the wall 35, and is held firmly upon the inner end of the pin, thus forcing the pin inwardly. The length of these pins 7 V is such that when the block A is retracted to the position in which one of its sides is in contact with the web 36 of the segment disk, the point of the needle is flush with, or in side the outer peripheral surface of the disl'n Adjustment of the block & away from the web 36 will force these pins outwardly, all 7 being adjusted alike.

The manner of securing this ad ustment IS in a measure immater al.

which bears against a plate 37, which is secured to the segment disk opposite the end of the block. This bolt is provided with a lock nut stat. The segment disk is provided The construction herein shown by which this 18 secured with a plate to which projects from one end of the segment, and has a. lip 46 which extends outwardly, and serves as a stop for the folded edge of the paper. This stop is provided upon one set only of the segmental.

disks.

Along with the guide fingers 2, comple} V mentary fingers 28 are provided- These fingers are of spring charactor, and are curved at their lower end, corresponding with the curved section 21 of fingers 2. .At

their upper ends they are secured upon a' block 2%, which'is mounted upon a shaft 25, r

so that a slight rocky movement is permissible. The free or swinging ends of these fingers tern'iinatc a short distance prior to their reaching the nearest point of approach 7 between the two sets. of segments 8 and 30.

The paper when discharged from between the feed rolls 12, 12 passes between the guide fingers 2 and 23. After passing the lower end of the fingers 23, it contacts with the stops 4.6 carried by one set of the segment disks. The segment disks 3 and 30 are separated to such a distance, and the feeding pins or needles 5 are projected enough, so that the needles enter the paper, those of each set penetrating approximately tothe middle of the folded section. The segments 3 and 30 are connected so as to make the same num= ber of turns, and, so as to bring their edges into registry. As the gears connecting these two shafts are of the same size, and as the segments are of different radii, the result is that one set of segments has a peripheral,

speed greater than that of the other. The:

my device, that the paper, at the time it is acted upon by these segments, occupy 'a position which is well inclined away from vertical, for a reason which will be later seen. I r I By reason of the greater peripheral speed of the segment over that of the segment 3, the lower half of the paper will be fed faster than the upper half, from which there will be a buckling action between the two halves of the paper, and the lower half will be discharged from between the segments before the upper half is discharged. The feeding action of the upperv segments 3 will terminate before the following edges of the upper half of the paper reach the discharge point.

The spring action of the under guide fingers 23, will cause them to spring upwardly against the paper, and grip it securely, thus holding this half of the paper temporarily. At the same time the advancing or folded edge of the paper section contacts with a stop 51 to permit enough of the paper beyond the point at which its following edge will be held between the. two

fingers 21 and 23. The lower half ofthe paper will, however, be discharged, and will fall away from the upper half then resting upon guide fingers 26.

In this condition the paper: has been opened and the upper half isbeing held for the insertion of the filler sections. lhese filler sections are being brought into position by the action of the feeding tapes 15 and 16. These filler sections, 17 and 18, are shown as being discharged between the two sides of the cover section 19 in Fig. 5.

The momentum of discharge of these filler sections will carry them forward until their advancing edges contact with the fold in the cover section. At this point, the stop 51 is removed to permit discharge of the stuffed paper. 1

Two setsof feed rollers 6 and 6-0 lie at opposite sides of the positionoccupied by the folded edge of the cover section while it is receiving the insert sections. One of these,

roller 66, which enters a camslot 67 of cam 68, carried by the shaft 31 upon which is mounted one set of the segmental disks. The

shape of this cam is such that the said roller 6, and the'stopi5l'which is carried thereby, are both raised during the time while the cover section is receivingxthe insert sections.

The'position of the stop 51 is such that, in.

this position of the roller 6, it is in the path At the time when the insert sections have reached the bottom of the cover section, thecam causes the cam roller, carried by the arm 64, to approach nearer the center, this causinga depression of the feed roller 6, and

the removal of the stop 51v from the path of the paper, thus releasingthe paper and applying pressure between the rollers 6 and 60 to discharge the paper.

Supplemental rollers present invention, I have shown nothing of the details thereof.

Ishave shown stops 7 and 7 0,which are controlled in such way asto check and control theiposition of the insert sections, and to time their entrance into the. stufiingchamber. These stops are of the character shown 610 are provided, which are connected with rollers 60. bya L r of the papers and prevents their passing .by.

in my application hereinbefore referred to,

and as their details of construction formno part of my present invention, I will not herein describe them.

The blocks 24 to whichthe fingers 20,123

are secured are adjustably fixed to shaft25, as by set screws 27. A coiled spring 28has one end fixed to a frame member and thewhich is normally held .by the spring against a fixed stop 29 to limit the angular position of the end of fingers 20.

One of each pair of feed members, asthe rolls 1, 10, 12, 13 and disks 30, is mounted to be spring held toward its complemental member, as by having: its shaft 32 mounted in a block 8 sliding'in guide waysSO under the action of springs 81. A bolt 82 with stop nut 83 limits the approach of thisroll to ward its mate. 7
